TYPE-WRITING MACHINE.

SPECIFICATION forming` part of Letters Patent No. 688,666, dated December 10, 1901. Application filed February 11, 1901. Renewed September 28! 1901. Serial No. 76,952. (No model.)

To @ZZ whom it may concern:

Be it known that I, CHARLES P. MOSHER, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania,have invented certain new and useful Improvements in Type- IVriting Machines, of which the following is a specification.

This application relates to the type-bar bear lo ings of writing-machines.

The main objects of my invention are to assemble a large number of type-bars in a small compass and to prevent lateral vibration of the bars while permitting them to swing I5 freely to and from the printing-point.

To these and other ends my invention consists in certain combinations of devices, features of construction, and arrangements of parts, all as Will be fully hereinafter set forth,

2o and particularly pointed out in the concluding claims.

In the accompanying drawings, Figure 1 is a fragmentary sectional front elevation of a front-strike writing-machine, showing my improvements applied thereto. Fig. 2 is a plan view of a slotted curved bar forming part of the, means for mounting the type-bar hangers. Fig. 3 is a face View of a type-bar hanger. Fig. 4f is a sectional view showing the method 3o -of mounting the hanger and securing the same after adjustment. Fig. 5 is a face View of a type-bar and its hanger. Fig. G is an edge view of a type-bar. Fig. 7 is a face View of a bracket,the bars attached thereto beingshown in cross-section.

In the several views similar partsare designated by similar numerals of reference.

Portions of the machine not necessary to the invention are omitted for the sake ofclearness. 4o The type-bar comprises a type-carrying arm or blade l and an enlarged thin hub 2, having a large eye 3, in which is cut an interior annular V-groove 4, forming bearing-su rfaces for a circular row or series of antifriction-balls 5. The hub is provided with a short perforated operating-arm 6, to which is attached the usual connecting-rod 7. The

type-bars are mounted upon hanger-plates 8, which have central perforations 9,so that they may be strung upon a rod or bar 10, which is 5o curved concentrically with the printing-point 1l and is secured at its ends in opposite brackets l2 by'means of nuts 13, which en-A gage the threaded ends of the rod, said brackets having arms 14, which may be secured by screws l5 to any suitable part of the typewriter framework, Which is designated as 16. Each hanger-plate has a radial portion or ear 17, which lits closely the concaved upper surface of a curved bar 18, which is parallel with 6o the bar 10 and is secured at its ends by screws 19 to the brackets 14E and is also longitudinally slotted at 20 to receive the Shanks of screws 2l, which are tapped into the ears 17, whereby the hanger-plates may be adjusted to any position along the bars l0 and 18 and there secured, so that there will be no liability of either lateral displacement Aor rotation of the hanger-plates. The bearing edges of the ears are cut concentrically with the central 7o perforations 9 in the hanger-plates, and the bar 18 is concaved to fit these rounded edges of the ears. Said ears may, however, be otherl wise shaped and secured in position.

Upon each hanger-plate is formed opposite laterally-projecting tapering bosses or cones 22, each of which coperates with a contigu- V ous cone upon the adjoining hanger-plate, so as to form an annular V-shaped groove or bearing for cooperation with the interior an- 8o nular V-groove 4f, formed in the type-bar, the hub of said type-bar being of course disposed between the adjoining hanger-plates and surrounding the bar 10. WVhen assembled, the V-grooves formed by each pair'of adjacent 85 cones lie in planes which are radial to the common printing-center, the contiguous cones being parallel, so as to form a uniform runway for the balls, and the cones upon the opposite sides of each hanger-plate slightly con- 9o verging, as at Fig. l. The axis of each cone is tangential to the curve of the segment, and hence the axesof the opposite cones upon a hanger would intersect, if produced.

In assembling the parts the hanger-plates and type-bars may be strung alternately upon the rod 10, the balls being placed in position, and then themass of hangers may be crowded together by any suitable means, so as to adjust the bearings of all the balls and cause the type-bars to be steadied against lateral vibration and at the same time enable the type-bars to vibrate freely to the printingpoint. In order to secure the hangers and type-bars in their adjusted position,the screws 21 are tightened.

It will` be seen that the series of hangerplates serve as struts connecting the bars l0 and 18, so that said bars are firmly secured together, and the whole forms an exceedingly rigid structure in which there is no liability of yielding during the vibration of any typebar. It will also be seen that I have provided a hanger which is formed on opposite sides with type-bar bearings which are in the form of cones or tapering bosses and that two adjacent bearings oi.y contiguous hangers coperate together to support one type-bar, that these contiguous bearings form a circular V- shape groove which receives a set of antifriction balls that also run in the V-shape groove of the type-bar supported by said pair of contiguous bearings, that the type-bars supported on opposite sides of a single hanger vibrate in different radial planes to a common printing-center, that each type-bar is supported by a single series of bearing-balls which run in a race formed by the V-groove in the typebar and by the V-groove formed by the pair of contiguous cones, that theseries of hangers or supports alternate with the series of type-bars and that the adjacent sides of two independent hangers support one type-bar, that means are provided for laterally adjusting the cones or bearings and also for adjusting the hangers or supports, that the series of hangers and cones are arranged in a curve about the printing-center and are supported upon a curved device or rod upon which they may be adjusted laterally and then secured, that the hangers and cones are perforated centrally for Stringing and adjustment on said curved rod, that there is provided a second curved rod or bar to which each plate or hanger is connected by screws,that one curvedl bar passes through the hubs of the type-bars and through the plates or hangers and through the cones or bearings, and that the other curved bar and fastening-screws prevent said plates from turning, while said screws also preserve the lateral adjustments of the plates.

It' desired, the hangers may be of different formation and otherwise supported,'and many other variations may be made in construction and arrangement within the scope of the invention. Parts of the invention may be used without others.

WVhat I claim as new, and desire to secure by Letters Patent, is-
